Abstract

A disposable syringe having a plunger (20) which is movable within a barrel (170), a needle carrier (80) to retain a needle (300), and, a connection means (70) attached to the plunger. In use, upon depression of the plunger (20), the connection means (70) engages the needle carrier (80). This is achieved such that there is angular displacement of the needle carrier (80) relative to the longitudinal axis of the syringe. Therefore, upon subsequent withdrawal of the plunger (20) the needle carrier (80) becomes housed in the barrel (170) in a canted manner.
